Hey @jainankitk -- I brought this up on the dev list last year here: https://lists.apache.org/thread/jxczhgn5loqwn10xrb30k2hg0jrbovcs As Adrien called out in that thread, you can use `nextClearBit()` to step through the deleted docs, but as I called out, that's `O(maxDoc)`. I had the idea of storing an array of doc IDs, but that would require a binary search to do random lookups. Uwe had a nice idea of using a `SparseFixedBitSet` if the number of deletes is small, which I think would give us the best of both worlds (`O(1)` random access and `O(deletedDocs)` traversal). -- This is an automated message from the Apache Git Service.
